Patented Dec. 27, 1932 STATES CYRUS C. JOHNSON, OF SALINA, KANSAS BURNER Application filed lTanuary 6, 1931'.

rhis invention relates to burners designed for burning gas, the primary object of the invention being to provide a burner of such a construction that the gas entering the burn- 5 er will be evenly spread throughout the entire circumference of the head of the burner, to

insure a thorough mixing of the gas and air at the burner head, resulting in complete combustion, and consequently increasing the eliiciency of the burner.

An important object of the invention isthe provision of a burner having a head against which the gas contacts on entering the burner, the construction of the head being such as to permit an unobstructed passage of the gas into the fire bowl.

A further object of the invention is to provide a burner which may be readily and easily positioned within the irebox of a furnace, the usual furnace grate providing the support for the burner, thereby eliminating the necessity of reconstructing the usual furnace firebox, to install the burner.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a fragmental sectional view through a firebox and gas burner constructed in accordance with the invention.

Figure 2 is a plan view of the burner.

40 Referring to the drawing in detail, the reference character 5 designates the iireboX of a furnace in which the usual grate 6 is supported. The burner forming the essence of this invention is so constructed that it 45 rests directly on the lire grate 6. The burner comprises a body portion 7 which is hollow and is formed with a downwardly inclined outer wall 8, the upper surface of the body portion being depressed to form the burner 50 bowl 9.

Serial N0. 507,023.

An opening is formed in the upper surface of the body portion, over which opening one end yof the air delivery tube 10 is mounted, the delivery tube being in the form y of an elbow'having its discharge end di- 55 rect-ed downwardly at the center of the bowl,

as clearly shown by Figure 1 of the drawing. Thusit will be seen that due to this construction, air may enter the hollow body portion, betweenv the grate bars in the usual way, from where the air may pass upwardly into the tube 10 and be directed downwardly into the burner bowl 9.

The. reference character 11 designates the gasV feed pipe which extends upwardly G5 through the grate, and through an opening formed substantially centrally of the burner bowl 9, the upper end of the pipe 11 being formed with external threads to accommodate the threads of the supporting ring 12 70 which is shown as positioned thereon. Depressions are formed in the upper surface of the supporting ring 12 and are of such construction that thev accommodate the lower ends of the supporting fingers 13 that are formed integral with the head 14, the fingers being of lengths to support the head 14 in spaced relation with the upper end of the pipe 11.

As clearly shown by the drawing, the head is concavo-convex so that the air which is di. rected to the upper surface thereof, will be spread laterally, while the gas: which enters the burner through the pipe 11 will strike the under surface of the head and be spread lat- 35 erally to miX with the air at the lower edge of the head.

Due to the manner of supporting the head 13, it will be obvious that the gas will have an unobstructed passage from the pipe, the flow of gas through the pipe being, however, regulated by means of a suitable valve not shown.

Fire clay, or other suitable material indicated by the reference character 15 is positioned within the firebox to cover the space between the barsV of the grate, between the body portion 7 and inner surface of the fireboX, confining the air to that portion of the grate directly under the body portion 7.

The reference character 16 designates the usual tire bricks employed in furnace frebox lining construction. It might be further stated that the construction of the burner is such that by reducing the How of gas through the pipe 11, the pipe l1 may be employed as a pilot light.

In the operation of the burner, gasV passing through the pipe 1l strikes the concaved surface of the head, and due to its unobstructed passage laterally, the gas is spread evenly throughout the entire under surface of the head, and passes from the underside of the head, Where it mixes with the air directed to the outer surface of the head, by the tube 1 0. A thorough and complete combustion of the gas is insured, to theend that an exception ally hot lire is provided.

I claim: A y

In a burner, ra grate, a hollow body portion mounted on the grate to receive air through the grate, the upper surface of the body portion being formed with a depression providing a burner bowl, a gas feed pipe extending through the center of the bowl, a supporting ring on the. upper end of the pipe, said ring having depressions, a burner head, fingers formed integral With the head and resting in the depressions to removably support the head, and a delivery tube communicating with the hollow1 body portion and extending vto a point directly above the head to deliver air thereto` and the Wall of the body portion sloping outwardly towards the grate.

In testimony that I claim the foregoing as my own, I have hereto aiXed my signature.
